Finally got it done - GLK250 DPF/SCR Deleted and EGR disabled
I have a dire need to terminate the EGR, DPF, and SCR systems in my 2014 MB E250 (OM651).
I'm hopeful that the kit designed for the GLK 250 mentioned in the GLK 250 thread here will be compatible with my E-Class sedan. See pdf showing current problem and exhaust pictures.
I investigated this last year due to some temporary problems with the DEF system that strangely disappeared with time and following stricter DEF top-off routines. At that time I did not see a good fit solution for my vehicle
Today, my luck is not so good. The crude diagnostics I have available indicate the DPF is clogged and likely one (or more) exhaust sensor malfunctions. The vehicle is currently in limp home mode.
Do you have any advice on preparations for the modification and the maintenance routines that one should follow after the modification?
I live near Charlotte, NC. I am reaching out to several providers within 150-miles to quote the service. It seems like (RawTek/Malone) or (Buzzken/JR) are my options.
I appreciate any information you all have shared on your experience having completing the modification.
I can vouch for OETuning as a good, permanent solution. I'm not affiliated with them in any way. They may provide discounts for MBworld forum members. Currently running their software and couldn't be happier, nothing needs to be chopped off the car either. You just flash the tune in your garage/driveway and you're set. Here's the site and info: https://www.oetuning.com/products/me...glk250-bluetec and I would call or email them to ask about discount before purchasing.
Good luck.

No issues with the delete so far except rough idle during the cold start. I believe that something to do with my injectors are getting clogged. I am currently having a leak in my brake system. I am gonna get Sam to check it out and get the leak repair. Other than that GLK still running strong

I ordered a new filter which I will put in this week and now am considering repiping the DPF altogether or boring out the filter itself.

it's the tune. get them to re work the tune.
Can you please share where did you get Stage 1 tune with full delete done?
Thanks
I did just empty my DEF tank though, drained probably 6 gallons of the stuff. Any bit of weight savings is a win in my book.

Monitoring the DPF pressure differential for the past year reveals a 0.1 PSI difference. That is to say, none.
To make matters worse, some tuners disable important safety items to prevent any error codes from popping up ever again. I heard recently from an expert in the field that he found a tune with more than 1400 individual trouble codes disabled in a vehicle. It ran like crap but never lit up the CEL, and the poor owner had no idea what was going on or where to start fixing since the ECU wasn't spitting out any codes.
Just making the point that quality is important, and not all tuners are on the up and up. YMMV...
Thank you.
